Pierre Choderlos de Laclos

Pierre Choderlos [ʃodɛrlo] de Laclos (1741-1803) was a career military man, both before and after the Revolution, but he also tried his hand at writing, and succeeded in creating a sensation with his epistolary novel Les Liaisons dangereuses (1782).

Examples of the conditionnel concessif from Chloderlos de Laclos's famous epistolary novel of 1782. Some involve the conditional present introduced by quand (rather than the imperfect indicative introduced by si), and some involve the imperfect subjunctive.
